a GDL 69/69A, GDL 88, GTX 345, or GSR 56 and an appropriate Weather
subscription. Only one weather source can be displayed at a time (i.e., FIS-B

8.1.1.6 Stormscope
®
(Optional)
The WX-500 Stormscope Weather Mapping Sensor is a passive weather
avoidance system that detects electrical discharges associated with thunderstorms
within a 200 NM radius of the aircraft. The Stormscope measures relative
bearing and distance of thunderstorm-related electrical activity and reports the
information to the display. Stormscope and XM Lightning are mutually exclusive.
NOTE
: The Stormscope map overlay is only displayed if valid aircraft heading
information is available. Refer to the WX-500 Pilot’s Guide for a detailed
description of the Stormcope WX-500.
